The sparks producing means 30 comprises a piezoelectric unit 31, which is disposed in the lighter housing 10 for generating piezoelectricity, comprising a movable operating part 311 extended upwardly and an ignition tip 312 extended to a position closed with the nozzle head 21 of the gas nozzle 20, wherein when the movable operating part 311 is depressed downwardly, sparks are generated from the ignition tip 312 to ignite the gas emitted from the nozzle head 21 of the gas nozzle 20 at the same time.

The ignition actuator 40 is slidably mounted on the sidewall of the lighter housing 10 and is attached to a top end of the movable operating part 311 of the piezoelectric unit 31, wherein the ignition actuator 40 comprises a pusher button 41 slidably mounted on the sidewall of the lighter housing 10 along the guiding slot 13 and a depressing arm 42 extended into the lighter housing 10 to rest on the depressible end 232 of the gas lever 23 in such a manner that when the pusher button 41 is depressed downwardly, the movable operating part 311 of the piezoelectric unit 31 and the depressible end 232 of the gas lever 23 are respectively depressed at the same time to generate the sparks and to release the gas so as to ignite the lighter.

The utility tool 51, which is embodied as a cutter, is retractably received in the tool cavity 12 of the lighter housing 10 and is adapted to extend out of the lighter housing 10 through the tool sliding slot 14. Accordingly, the lighter housing 10 further comprises a sliding track 15 upwardly extended to the tool cavity 12, wherein the utility tool 51 has a sliding portion 511 slidably coupled with the sliding track 15 and a utility portion 512 which is integrally extended from the sliding portion 511 and is arranged when the sliding portion 511 is upwardly slid along the sliding track 15, the utility portion 512 of the utility tool 51 is upwardly slid out of the lighter housing 10 through the tool sliding slot 14, as shown in FIG. 3. It is worth to mention that the utility tool 51 can be embodied as a handy tool, such as a screw driver, a cigar cutter or a letter opener, adapted to be retractably received in the lighter housing 10 in a hidden manner and to be extended out of the lighter housing 10 to provide an added function of the lighter.

The actuation unit 52 comprises an actuation button 521 integrally formed at the pusher button 41 of the ignition actuator 40 and a pusher lever 522, which is pivotally supported in the tool cavity 12, having a pusher end 5221 engaging with a bottom end of the sliding portion 511 of the utility tool 51 and a control end 5222 arranged in such a manner that when the actuation button 521 is depressed downwardly to depress the control end 5222 of the pusher lever 522, the pusher end 5221 of the pusher lever 522 is pivotally lifted up to push the utility tool 51 upwardly so as to upwardly slide the utility portion 512 of the utility tool 51 out of the lighter housing 10 through the tool sliding slot 14. Accordingly, the control end 5222 of the pusher lever 522 is coupled with the depressing arm 42 of the ignition actuator 40 such that when the depressing arm 42 of the ignition actuator 40 is depressed, the control end 5222 of the pusher lever 522 is depressed to pivotally lift up the pusher end 5221 thereof.

In other words, the actuation button 521 is integrally formed with the pusher button 41 such that the actuation button 521 functions a universal button that operates both the ignition of the lighter and the utility tool 51 at the same time by one simple downward pushing action.

It is worth to mention that the actuation button 521 and the pusher button 41 can be embodied as two different independent buttons spacedly sliding on the lighter housing 10 to independently operate the ignition of the lighter and the utility tool 51.

As shown in FIGS. 1 through 3, the actuation unit 52 further comprises a resilient element 523 supported within the tool cavity 12 of the lighter housing 10 for applying an urging force against the utility tool 51 so as to retain the utility tool 51 in the storage position. According to the preferred embodiment, the resilient element 523 comprises a compression spring having two ends biasing against a top inner wall of the lighter housing 10 and the utility portion 512 of the utility tool 51 for downwardly pushing the utility tool 51 into the tool cavity 12 of the lighter housing 10. Therefore, when the actuation button 521 (the pusher button 41) is pushed upwardly after the ignition of the lighter, the utility tool 51 is pushed back to its original position so as to retract the utility tool 51 back to its storage position.

According to the preferred embodiment, the actuation unit 52 further comprises a pivot presser 524 having a pivot end 5241 pivotally mounted to the lighter housing 10, a presser end 5242 coupling with the pusher button 41 to drive the depressing arm 42 downwardly, and a depressing driver 5243 provided between the pivot end 5241 and the presser end 5242 to rest on the piezoelectric unit 31 such that when the pusher button 41 is depressed, the depressing arm 42 is depressed by the presser end 5241 while the piezoelectric unit 31 is depressed by the depressing driver 5243 at the same time. It is worth to mention that since the pusher button 41 (the actuation button 521) is driven to depress the piezoelectric unit 31 and to lift up utility tool 51, the user must apply enough downward force on the pusher 41. Therefore, the arrangement of the pivot presser 524 substantially reduces the downward force on the pusher button 41 that requires to depress the piezoelectric unit 31 and to lift up utility tool 51.

FIGS. 4A and 4B illustrate an alternative mode of the utility tool arrangement 50A which provides two action levels for operating the ignition of the lighter and the utility tool 51A. As shown in FIG. 4A, the actuation unit 52A comprises an actuation button 521A integrally formed at the pusher button 41 of the ignition actuator 40 and a pusher lever 522A, which is pivotally supported in the tool cavity 12, having a pusher end 5221A engaging with a bottom end of the sliding portion 511A of the utility tool 51A and a control end 5222A arranged in such a manner that when the actuation button 521A is depressed downwardly to depress the control end 5222A of the pusher lever 522A, the pusher end 5221A of the pusher lever 522A is pivotally lifted up to push the utility tool 51A upwardly so as to upwardly slide the utility portion 512A of the utility tool 51A out of the lighter housing 10 through the tool sliding slot 14.

The control end 5222A of the pusher lever 522A has a slanted sliding surface 5223A slidably engaging with the depressing arm 42 such that when the actuation button 51A (the pusher button 41) is depressed downwardly, the control end 5222A of the pusher lever 522A is depressed to pivotally lift up the pusher end 5221A thereof so as to only push the utility tool 51A out of the lighter housing 10 through the tool sliding slot 14, as shown in FIG. 4A. The actuation button 51A is adapted to be further depressed downwardly to slide the sliding surface 5223A of the pusher lever 522A along the depressing arm 42 until the movable operating part 311 of the piezoelectric unit 31 and the depressible end 232 of the gas lever 23 are respectively depressed at the same time to generate the sparks and to release the gas so as to ignite the lighter, as shown in FIG. 4B. In other words, the actuation button 51A controls the ignition of the lighter and the utility tool 51A at two depressing action levels. Therefore, the user is able to selectively operate the ignition of the lighter and the utility tool 51A by one single button (the actuation button 51A and the pusher button 41). Accordingly, the depressing arm 42 has a corresponding slanted surface 421 engaging with the sliding surface 5223A of the pusher lever 522A for allowing the control end 5222A of the pusher lever 522A to freely slide along the depressing arm 42 when the actuation button 51A is further depressed downwardly for ignition.

It is worth to mention that the functional lighter can be incorporated with flint-and-striker wheel structure to form a flint type lighter by simply replacing the piezoelectric unit 31 with a flint and a striker wheel to generate the sparks when the striker wheel is driven to rotate against the flint. In which, the pusher button 41 is formed at the depressible end 323 of the gas lever 23 for releasing the gas. In addition, the actuation button 521 is slidably mounted on the lighter housing 10 to only operate the utility tool 51. Therefore, the ignition of the lighter and the utility tool 51 are independently operated by the pusher button 41 and the actuation button 521 respectively.
